1.55 Ct. Green Grossular Garnet from Tanzania

This 1.55 carat cushion shaped green grossular garnet from Tanzania presents a study in precision faceting and natural color, offered by The Natural Gemstone Company. The gem measures 7.41 x 5.65 x 4.30 mm, a proportion set that emphasizes face up presence while maintaining balanced pavilion depth. The cutter employed a mixed brilliant strategy, combining a brilliant style crown with a modified pavilion arrangement to marry dispersion with controlled light return. The cushion outline preserves the classic softened square silhouette, and the facet architecture yields an appealing interplay of scintillation and windowing. The polish quality is excellent, evident in crisp facet junctions and mirror like facet planes that maximize internal reflection. The clarity grade is slightly included, evaluated at eye level, and these natural inclusions act as internal fingerprints, providing authentication without significantly compromising transparency or brilliance in typical viewing conditions.

From a gemological perspective this grossular garnet demonstrates the optical behavior expected of the grossular group, with refractive characteristics that sit in the low to mid one point seven range, and with a relatively modest dispersion compared with high dispersion gems. The mixed brilliant cut has been executed to optimize what dispersion there is, concentrating bright flashes on the crown while the pavilion facets create contrast and depth. The medium color intensity is a vibrant mint to lime green tone that reads lively under both daylight and warm indoor lighting, and the hue balance is consistent across the table with minor zoning that can be seen in certain orientations. No enhancements have been applied, the stone is natural and untreated, which is significant for collectors who prioritize original state gems, and provenance from Tanzania adds geological context and desirability for those tracking source specific material.

When comparing this natural grossular garnet to lab grown counterparts it is important to consider differences in formation, trace element distribution, and long term value attributes. Lab grown stones offer predictability, uniform clarity, and often lower price points due to controlled growth conditions, however they lack the complex inclusions and subtle color variability that are intrinsic to natural crystals formed under fluctuating geological conditions. The slightly included nature of this garnet is not a defect in the way that uniformity in lab grown material is presented, but rather an identifier that contributes to the gemological story of the piece, and for many buyers this narrative has intrinsic value. Natural stones like this garnet also tend to retain or appreciate in market value over long horizons when well documented, especially when they are unenhanced and accompanied by reliable sourcing details, attributes that The Natural Gemstone Company documents and stands behind.

For practical application in jewelry the 7.41 x 5.65 x 4.30 mm cushion lends itself to solitaire ring settings, halo designs, and bespoke pendant work, with the mixed brilliant faceting offering lively sparkle under movement and an excellent polish ensuring a refined finish under loupe and to the naked eye. Grossular garnet has durability adequate for everyday wear when properly set, with Mohs hardness in the neighborhood of six point five to seven point five depending on exact composition, and stable color that does not require special care beyond standard precautions against harsh chemicals and abrasive contact. Collectors and designers will appreciate the combination of natural origin, no enhancement, and expert cutting that delivers a green grossular which is both technically interesting and immediately wearable, available through The Natural Gemstone Company.
